Anthurium plant named ‘ANTHETAAD’

ABSTRACT

A new  Anthurium  plant named ‘ANTHETAAD’ particularly distinguished by having shiny, blistered, red, oblong-cordate, and very durable spathes that retain the original color for a very long period of time, dark green and elliptical-cordate, durable leaves, white spadices with yellow tips, early and rich flowering continuously throughout the year, and a plant height of 40.0 cm to 45.0 cm is disclosed.

Genus and species: Anthurium andraeanum L.

Variety denomination: ‘ANTHETAAD’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Anthurium, botanically known as Anthurium andraeanum L., and hereinafter referred to by the variety name ‘ANTHETAAD’. The new Anthurium plant is a product of a planned breeding program conducted by the inventor in Bleiswijk, the Netherlands. The objective of this breeding program was to create a new plant with a height of 40.0 cm to 45.0 cm having shiny and blistered, red, oblong-cordate, and very durable spathes.

The new variety originated from a cross-pollination made in July 2008 in Bleiswijk, the Netherlands. The female parent was a pink Anthurium pot plant designated ‘8417-01’ (unpatented), and the male parent was a red Anthurium pot plant designated ‘11985-01’ (unpatented).

A single plant was selected from the progeny of the stated cross in July 2010. Asexual reproduction of the new variety by tissue culture in 2012 in Bleiswijk, the Netherlands, has demonstrated that the new variety reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations.

Community Plant Variety Rights for this variety have been applied for in the European Union on Nov. 27, 2017, by Applicant who obtained the subject matter disclosed directly from the inventor. ‘ANTHETAAD’ has not been made publicly available or sold anywhere in the world prior to the effective filing date of this application with the exception of sales or disclosures made one year or less before the effective filing date of this claimed invention by Applicant who obtained ‘ANTHETAAD’ directly from the inventor.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Bleiswijk, the Netherlands:

-   -   1) Shiny and blistered, red, oblong-cordate spathes;     -   2) White spadices with yellow tips; and     -   3) Green, elliptical-cordate leaves.

DESCRIPTION OF THE PHOTOGRAPHS

This new Anthurium plant is illustrated by the accompanying photographs which show the overall plant habit including blooms and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a 44-week-old plant grown in a greenhouse in Bleiswijk, the Netherlands, in January 2020. Colors in the photographs may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety.

FIG. 3 shows a close-up of the upper leaf blade surface.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctive characteristics of ‘ANTHETAAD’. The data which define these characteristics were collected from asexual reproductions carried out in Bleiswijk, the Netherlands. The plant history was taken on 44-week-old plants which were planted from tissue culture in 14-centimeter (diameter) pots and grown in a glass greenhouse between 19° C. and 24° C. Observations were made in January 2020. Color readings were taken under 5000 lux natural light in the greenhouse. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2015).

More blossoms             appear after some additional weeks so that a full flowering             and commercial plant will have 7 to 8 red spathes. Smaller             blossoms may occur on immature plants. -   Spadix:     -   -   Size.—Length: 3.5 cm to 4.5 cm (depending on flower size).             Width (at apex): 0.6 cm to 0.7 cm.

When the spadix matures, small stigmata protrude. The             stigmata are evenly distributed around the spadix. The             spadix matures from base to top, slowly giving the spadix a             somewhat rough appearance.         -   Color.—Immature: RHS 155B. Mature: RHS 17A.

COMPARISON WITH PARENTAL AND SIMILAR COMMERCIAL VARIETIES

‘ANTHETAAD’ differs from the female parent plant ‘8417-01’ (unpatented) in that ‘ANTHETAAD’ has red, oblong-cordate spathes in an upwards direction, whereas ‘8417-01’ has pink, orbicular-cordate spathes in a horizontal direction.

‘ANTHETAAD’ differs from the male parent plant ‘11985-01’ (unpatented) in that ‘ANTHETAAD’ has free (non-touching) spathe lobes, whereas ‘11985-01’ has overlapping spathe lobes.

‘ANTHETAAD’ differs from similar commercial variety ‘ANTHDASZUM’ (U.S. Plant Pat. No. 29,721) in that ‘ANTHETAAD’ has green cataphylls, elliptical-cordate leaves, and undulated spathe margins, whereas ‘ANTHDASZUM’ has red-brown cataphylls, narrow long-cordate leaves, and entire spathe margins.

‘ANTHETAAD’ differs from similar commercial variety ‘ANTHABUDON’ (U.S. Plant Pat. No. 20,282) in that ‘ANTHETAAD’ has green cataphylls and undulated spathe margins, whereas ‘ANTHABUDON’ has purple-red cataphylls and entire spathe margins. Additionally, ‘ANTHETAAD’ has fewer flowers per spadix than ‘ANTHABUDON’. 

I claim:
 1. A new and distinct variety of Anthurium plant named ‘ANTHETAAD’, substantially as illustrated and described herein.
